Ukraine will screen one million civil servants for loyalty to the new government, Prime Minister Arseny Yatseniuk says, reports GHN based on BBC.
The government passed a new law on Tuesday, allowing the vetting of government officials and the removal of corrupt officials.
Mr Yatseniuk said all departments who worked under previous President Viktor Yanukovich would be vetted.
Ukraine has had months of unrest since Mr Yanukovich was ousted in February.
Government troops had been fighting pro-Russia separatists in the east for months, until a truce was signed on 5 September.
"One million civil servants of different kinds will come under this law, including the whole cabinet of ministers, the interior ministry, the intelligence services, the prosecutor's office," Mr Yatseniuk said in a televised cabinet meeting.
